React Server Components - The Mental Model Shift

Short summary

A production-experienced deep dive into React Server Components as an architectural shift, not a performance trick. The article covers the asymmetric server/client boundary, how RSC changes data fetching from page-level to component-level, and the architectural costs of distributing data access across the component tree. It argues for a service/repository layer to maintain clean separation and explains bundle composition benefits through concrete scenarios.

• •RSC creates a genuinely asymmetric server/client boundary with real architectural consequences
• •Data fetching moves from page boundaries to individual components, requiring new discipline
• •Recommends service/repository layers to prevent data logic from bleeding into rendering
